I'm not sure when you are going in March, but with that being Easter month this year, I think I'd plan at least some Priority Seatings. I'd figure out a couple of sit down resturants I'd like to eat in, decide which meal and which day, and call and make priority seating for that time. If you don't and it's busy, you could be standing in long lines to get counter service food, or eating at really early or late times, and still waiting long to get seated.
